Detailed Description
In order to make the technical solutions of the present invention better understood, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The invention will be described in more detail below with reference to the accompanying drawings. Like elements in the various figures are denoted by like reference numerals. For purposes of clarity, the various features in the drawings are not necessarily drawn to scale. Moreover, certain well-known elements may not be shown in the figures.
In the following description, numerous specific details of the invention, such as structure, materials, dimensions, processing techniques and techniques of components, are set forth in order to provide a more thorough understanding of the invention. However, as will be understood by those skilled in the art, the present invention may be practiced without these specific details.
Example 1:
as shown in fig. 2 to 7, the present embodiment provides a mask plate assembly, including:

The supporting mask plate 2 is arranged on the frame 1 (namely, the shielding mask plate is formed), the glass substrate to be subjected to evaporation is arranged on the supporting mask plate 2, and thus, evaporation materials pass through the opening part 11 of the frame 1 and finally reach the glass substrate through the supporting mask plate 2 to form specific patterns.
Wherein, the first aligning holes 121 of the frame 1 correspond to the second aligning holes 221 for supporting the mask 2 one by one, so that the frame 1 and the mask 2 are aligned; and the second aligning holes 221 for supporting the mask plate 2 correspond to the aligning holes on the glass substrate one to one, so that the glass substrate is aligned with the frame 1 through supporting the mask plate 2, thereby ensuring the position accuracy of the evaporation patterns.
It should be noted that, because the thickness of the frame 1 is relatively large, for example, 20 to 30mm, the precision of the frame 1 is relatively low, and inaccurate alignment may be caused if the frame 1 directly passes through the first alignment hole 121 of the frame 1 to align with the alignment hole on the glass substrate; and support 2 thickness of mask plate thin, if 20 ~ 50um to support the precision height of mask plate 2, if the second counterpoint hole 221 through supporting 2 of mask plate is the hole counterpoint with the pair of glass substrate, then can guarantee that frame 1 and glass substrate's counterpoint is accurate, thereby guarantees the position accuracy of coating by vaporization pattern.
Further, the frame 1 may be formed of an indium tile or a nickel-iron alloy material; the support mask 2 may be formed of an indium tile or a nickel-iron alloy material. The diameter of the first registration hole 121 is slightly larger than the diameter of the second registration hole 221.
